我为此奋斗了一周+阅读了约 100 篇文章，但仍然无法解决。
ThinkPad P50 上的 Kubuntu 16.04 带有两个 NVME 磁盘，位于 raid1 + nvidia M1000M（使用 nouveau）。由于 grub 无法安装在 raid 中的 NVME 磁盘上（计算偏移量时出现错误），我从第一个磁盘的小物理分区启动，然后使用另一个 raid1 加密分区来存储 /home 和其他分区。
我的问题是挂起不起作用。当我尝试：pm-suspend，或 echo mem > /sys/power/state 或 systemclt suspend
它工作正常（不幸的是，并非总是如此，但总是与 /sys/power/state 一起），但当我尝试从挂起状态返回时，我甚至得到了 GUI，但它挂起了。我可以切换 ALT+CTRL+F1，登录，然后看到 raid1 故障和大量中断，导致 LoadAverage 增长到 10+。进一步检查 syslog 表明，所有组件都从挂起状态返回，但主磁盘除外，我确实有以下错误：

/cat/proc/mdstat 还确认一个磁盘已从 raid1 (_U) 中移除。
尝试过的内核：4.8.2、4.8、4.6、默认（4.4）。尝试过的内核选项：nomodeset（实际上它无法与 nouveau 配合使用）、noapic、nolapic（已删除，无法用它启动）、acpi_osi=Linux（也是空的）。
问题还是一样。BIOS 升级到最新版本（当前版本）。
我是否应该假设 NVME 磁盘在 Linux 中还没有得到很好的支持？在 Apple macosx 下，nvme 磁盘的暂停工作正常，但我那里只有一个 - 所以也许这与 mdadm/raid 有关？
请帮忙。
谢谢，Michal
根据要求我正在添加日志。
我已于 9:24:41 执行了 pm-suspend。之后屏幕一片空白，只有硬重置才有用。

在 9:25:26 时，我们已经可以看到硬重启后的消息 - 所以系统日志中没有什么有趣的东西。这次我没有 NVME 磁盘日志错误，只有在使用 /sys/power/state 暂停时才会出现错误（然后它几乎成功了，因为我可以回到系统/GUI，但磁盘无法恢复）。
X.org 日志中也没有什么奇怪的 - 日志与后续正确重启的日志相同。
哪里出了问题？为什么 pm-suspend 会杀死我的笔记本电脑，而 echo mem > /sys/power/state 几乎可以正常工作（磁盘除外？）
谢谢，
答案1
使用 GRUB
正如本文所提到的回答，这是一个已知错误。只需编辑文件/etc/default/grub并将此参数添加acpiphp.disable=1到 grub 配置变量中GRUB_CMDLINE_LINUX_DEFAULT即可阻止 ACPI 热插拔。但是，答案的 op 指出它不一定禁用热插拔。
保存文件后，更新您的 grub 引导加载程序。
$ sudo update-grub
无 GRUB（仅限 UEFI）
如果您不使用 grub 但有 UEFI 系统，您可以使用它efibootmgr来修改现有的引导记录。首先，只需输入以下内容即可检查您的引导记录：
$ sudo efibootmgr
BootCurrent: 0002
Timeout: 1 seconds
BootOrder: 0002,0024,0025,0026,0027,0016,0019
Boot0002* Ubuntu
Boot0016 UEFI OS
Boot0019 TS120GSSD
Boot0025* WDC WDS120G
Boot0026* debian
Boot0027* Force MP600
现在，您需要使用参数“nvme_core.default_ps_max_latency_us=0”更新 Ubuntu 启动记录。这会强制 nvme 驱动器尽快进入低功率状态，从而帮助机器进入挂起模式。但是，在某些情况下，唤醒可能会有所延迟。
要进行更改，请输入以下命令：
$ sudo efibootmgr -b 0002 -@ "nvme_core.default_ps_max_latency_us=0"
然后重启机器
$ sudo reboot
现在您可以无错误地暂停机器。
